Empty nest

Yesterday the sparrow chicks left their nest box. This is how it looks inside - filled almost up to the hole with moss, small branches and feathers. Btw. there was a second, unused nest halfway down, so probably this or another couple made an early attempt, but was discouraged by the weather or something.
